Frías, the medieval town in Burgos retaining its city title

The medieval town of Frías, located in the north of Burgos, Spain, maintains a unique historical status as a city. This distinction stems from 1435, when King Juan II granted the municipality the title of city, a recognition that remains part of its institutional identity.

Built upon the rocky outcrop of La Muela overlooking the Ebro River, the town's urban layout is defined by its defensive and vertical architecture. The historical center features stepped housing, timber-framed buildings, and balconies that adapt to the steep terrain, creating a silhouette of houses seemingly suspended over the slope.
